For third deposit Betspin casino offers 50% bonus, which is already not so bad offer because their wagering requirements is only 35x bonus. But also they giving 50 freespins on Aliens slot. And I could not say that it is best slot for freespins, but it is for deposit, I mean almost for free, and also their freespins are wager free, so it is very good offer.
I claimed this bonus with 20€ deposit. Another 10€ was credited to my balance as a part of deposit bonus. Wagering requirements was only 350€ and I think it is very good offer. It is good chances to wager 350 with 30 starting balance.
I start playing, and first game I opened was aliens. Their offer freespins on this game make job, and I just wanted to play this game a bit. I had feature twice, but like most times my soldier was killed by aliens very fast, without going good to good paying symbols with multipliers.
But quickly I left this game, and tried Fruit Case. Fruit Case was very bad in payout. Only 3 of a kinds, and countless amount of 3 of a kinds. Quickly I lost my balance, without even made half of a wagering requirements.
My 50 freespins was credited next day. Like usually Betspin casino informed me about this by email, so I was not required to login many times and check. This is good practice for casino. From 50 spins I won about 7$, which is of course not best result. Continue play, and had feature couple of times, but like usually my soldier seems have not enough skill to kill many aliens.
I rate this bonus with 10 stars.
